Trait R is a Mendelian trait in humans for tongue rolling. The allele for the ability to roll the tongue (R) is dominant over the allele for the inability to roll the tongue (r).If both a mother and father are heterozygotes with respect to this trait, what is the likelihood that their offspring will also be a heterozygote for that trait?O 100%O 25%O 75%O 0%O 50%

In humans, the gene for right-handedness is dominant to the gene for left-handedness. A man and a woman both heterozygous for this trait marry. What percent of their children can they expect to be right-handed? What percent left-handed? What are the genotypic and phenotypic ratios?
Match the pattern of inheritance to the appropriate term.
Incomplete Dominance and Codominance So far, we have been studying the inheritance of genes that show complete dominance. In other words, one allele is completely dominant over another. In some cases, such as incomplete dominance and codominance, one allele is not completely dominant over another or the alleles affect the phenotype equally. Examples of incomplete dominance include feather color in parrots (C*C* = blue, C'C = yellow, C*Cf = green) and hair texture in humans CC = curly; C'C' = straight; CC' = wavy Practice Problem 3: За. If a straight-haired man marries a curly haired woman, what are the predicted genotypes and phenotypes of their children? If a parrot with yellow feathers is crossed with a parrot with green feathers, what are the predicted genotypes and phenotypes of their offspring? 3b.
ABO blood group is co-dominant for AB and O is recessive. Rh (+/-) factor is completely dominant. A man with O/positive blood and a woman with A/negative blood have six children. All of their children have A + blood type. What can you conclude about the parents’ genotypes? Group of answer choices Both mother and father are likely homozygous at both loci Mother was homozygous at the ABO locus but heterozygous at the Rh factor locus Father was homozygous at the ABO locus but heterozygous at the Rh factor locus Mother was heterozygous at both loci

At a different gene locus, the allele for hitchhikers thumb (D) is dominant to the allele for non-hitchhikers thumb (d). A man is heterozygoous for the traits and marries a woman who has no widows peak and is heterozygous for hitchhikers thumb. What fraction of this couples children should have a widow's peak and a hitchhiker's thumb? 3/8 1/4 1/2 3/4 0 A2)The allele for widows peak (H) is dominant for the allele for no widows peak (h).
